Hi Coaw-Lin and thanks for the video.  
Are you able to expand on the video to show how a release package can be created for a multi-project solution to create a single package with multiple dlls?

Hi Jason,  
To create a single package with multiple dlls in a multi-project solution, you can add multiple File elements and specify the path to each of your dll)  
In the following example, OpenTap.Plugins.SamplePackage project and OpenTap.Plugins.SamplePackage2 project are added as project reference in SamplePackage project.
